What is TextMuncher?
TextMuncher is a browser extension and web app that extracts text from ebooks you're reading in the browser. The extension automates page-turning and screenshot capture in Kindle Cloud Reader, then built-in OCR converts the captured pages into clean, plain text — ready to paste into ChatGPT, Claude, study notes, or research documents. The first 30 pages are free; Pro is $9.99 per month, or $48 per year, for unlimited automated capture.
The web app at textmuncher.com also accepts manual screenshots from any browser-based reading platform, plus EPUB files you own — EPUB extraction reads the exact text straight from the file — no OCR involved. Speed mode — the default for everyone — processes OCR locally in your browser. Optional Pro Quality mode sends only hard-to-read pages for a cloud second pass.
Cloud eBook Readers Block Everything
Copy-Paste Is Blocked
DRM restrictions block text selection and copy-paste in Kindle Cloud Reader and other platforms.
Manual Screenshots Take Hours
Screenshotting every page of a 300-page book is painfully slow and tedious.
One-Page OCR Tools Are Limited
Most OCR tools process one image at a time with no batch capability.
AI Tools Need Text, Not Images
ChatGPT and Claude produce better results with clean text input than with screenshot images.
